The PicoScope 5000 Series of Flexible Resolution Oscilloscopes has just been voted Test & Measurement Product of the Year by the judges of Electronics Weekly's Elektra Awards. The oscilloscopes were chosen for their usability as well as their performance.
The PicoScope 5000 Series scopes are the only oscilloscopes to provide selectable hardware resolution from 8 to 16 bits in a single device while maintaining low noise and distortion. They achieve this by using a novel digitizer architecture in which multiple high-resolution ADCs are sequenced in a variety of series and parallel combinations.
This great performance, combined with the advanced features of the PicoScope 6 software, means that the PicoScope 5000 Series is the only general-purpose oscilloscope that you need on your workbench.
Sampling rates and performance in the various configurations are as follows:
|Resolution||Max. sampling rate||THD||SFDR||Noise|
|8 bits||1 GS/s||< −60 dB||> 60 dB||120 μV RMS|
|12 bits||500 MS/s||< −70 dB||> 60 dB||110 μV RMS|
|14 bits||125 MS/s||< −70 dB||> 70 dB||100 μV RMS|
|16 bits||62.5 MS.s||< −70 dB||> 70 dB||70 μV RMS|
Full details and specifications of the PicoScope 5000 Series
Two PicoScope products have reached the final of EDN's Best-in-Test 2014 awards. The PicoScope 5000 Series Flexible Resolution Oscilloscopes (already winners of an Elektra award - see details above) are listed in the Handheld/Portable Test category, while the PicoScope 9300 Series Sampling Oscilloscopes feature in the Signal Integrity/High-Speed section. The new sampling oscilloscopes, with 20 GHz bandwidth and 64 femtosecond timing resolution, can analyze high-speed serial comms, semiconductors and interconnect - see details in next section.
EDN's editors were impressed by the scopes' 20 GHz bandwidth, equivalent to a rise time of 17.5 ps, which allows them to analyze high-speed electrical signals such as 10 Gbps Ethernet, 10x Fibre Channel, InfiniBand and PCI Express. Precision sampling circuitry gives these scopes a timing resolution of 64 femtoseconds.
Like all PicoScopes, the 9300 Series scopes are USB-connected, resulting in a compact instrument that takes up much less space than traditional benchtop machines. They also have a LAN port for remote operation.

Don't forget that our prize draw and charity donation scheme for product reviewers is still open.
It's easy to publish a review: choose a star rating and type in your comments. For the rest of this year, Pico will donate $1 towards a target of $1000 to Cancer Research UK, a registered charity, for every completed review. In addition, one lucky reviewer will be selected at random for a prize of $500 (or £300 or €350) in Amazon vouchers. The winner will be announced in the first Pico newsletter of 2014.
The donation scheme and prize draw end on 31 December 2013, so don't miss your chance.
Here are some of the latest tips delivered by our technical support experts. Keep watching our forum for more great ideas.
Q. Is it possible to trigger on two PicoScope input channels at once?
A. Yes, most PicoScopes can trigger on a combination of two or more inputs using a logical function such as A OR B.
Combining inputs requires the use of advanced triggers. First ensure that the channels you want to trigger on are enabled. In the triggering toolbar, set the trigger mode to Auto. The Advanced Triggers button to the right of the trigger mode control will then change from greyed-out to normal:
Click this button and select the Logic trigger type:
You can now set up the trigger level on each channel and then select a logic function such as OR to combine the channels. This will trigger on an event on any of the selected channels.
Q. How can I make PicoScope use a "roll mode" to continuously update the PC display?
A. PicoScope has a roll mode that it uses when the device is operating in streaming mode. To achieve this you need to do the following:
Switch the device to streaming mode, which happens at 100 ms/div or slower unless you have changed the 'Slow Sampling Transition' setting in Preferences.
Use a Repeat trigger.
Set the trigger level above the maximum signal level (or below the minimum) so that the scope never triggers.
PicoScope will now operate in a roll mode.
